We debated whether or not to put in two embryos. I was concerned for K's health (she has injured her back in the past) any the babies' health and, between you and me, am a little scared of two babies (let alone two babies all at once!). We went with two to increase our odds of getting pregnant, especially given the journey (emotional and physical) that this has been. Note: a recent study suggests that our logic on that isn't entirely sound.
We will know in an hour and a half!!
I've a garden, a garden of dreams,
Where the cool breeze whispering sways
Softly the apple-sprays
